Samyang 300mm f/6.3 overview

1Description

The silver Samyang Reflex 300mm f/6.3 ED UMC CS Lens is a mirror lens designed specifically for use on Fujifilm X mount cameras. The lens' Cassegrain design enables it to achieve a 450mm 35mm-equivalent focal length perspective within a compact and lightweight lens design that is significantly smaller than a traditional 300mm lens. It features a fixed f/6.3 aperture and manually focuses as closely as 2.95'.

One extra-low dispersion element and the inherent mirror construction of the lens work to eliminate chromatic aberrations while providing notable image sharpness and clarity. Furthermore, the UMC (Ultra Multi Coated) coating has been applied to reduce surface reflections, lens flare and ghosting while also contributing to improved overall contrast.

Mirror lens designed specifically for Fujifilm X mount cameras.

Catadioptric system with Cassegrain design helps to reduce the overall size of the lens while still providing a 35mm-equivalent focal length of 450mm.

One extra-low dispersion element and a UMC coating are integrated into the lens construction to improve sharpness and clarity as well as enhance the overall image contrast.

Samyang Reflex 300mm review-2015Before purchasing this lens I read through the other reviews and IMO agree with the other reviewers that this lens produces a reasonably sharp image at this price point. I shot a series of test images and found that if I applied the PS plug-in NIK Sharpener Pro and used Layer Masks to sharpen the in-focus area I could produce images that look very nice. The build quality of the lens is good and the focus ring operates very smoothly. The lens mount is precisely machined and fit onto my X-T1 without any problems. The lens comes with a pouch made of faux-leather and has no padding.

light, small, and sharpThe lens seems to be well built out of high quality plastic for the most part, with metal in critical locations. X-Mount is machined aluminum. Focus is the only control on this lens, and the rubber ribbing is wide and very easy to grip. It is not very heavy, and very small considering the focal length.This lens is slightly smaller than the Fuji 18-55 zoom, and the plastic 58mm filter thread is really more like 58.3mm, so my 58mm filter threaded onto it loosely and tended to bind up as I was unscrewing it. I'll be using this lens without a UV filter, but you should feel free to add a 58mm filter if you like. Filter thread size is NOT specified in the lens manual.This would be an ideal stealth telephoto lens if it were vibration-stabilized. Since it isn't, use of a rock-solid tripod is virtually essential when using this lens. Even then, the slightest motion of the camera during exposure (such as from the operation of the focal plane shutter in the Fujifilm X-E1) may impart motion blur to your capture.I recommend also setting shutter speed to faster than 1/500th second, and frequently this will mean using high ISO settings in the X-E1, and paying the penalty of less than maximum image quality. The alternative is blurry but high quality images. Hobson's choice, sort ofThe front of the lens rotates through about 150 degrees while focusing (the focus ring is most of the lens, including the front), hence Samyang provides a tubular lens hood as well as a nice soft pouch for storage. Focus ring rotation is very smooth and well-damped, but on my lens there is a very slight amount of play in the angular response, that is, if I rotate past the point of ideal focus then I have to turn back about 1 degree before the focus will change in the other direction. I believe this is normal play in the focus mechanism.High-contrast edges seem to acquire a slight haze around them, which disappears for the most part after downsizing. Overall image contrast is slightly low compared to the excellent Fuji 18-55 zoom, but this is easily corrected during post processing.

About as good as a reflex lens can getFor the money, this is a great telephoto lens. You sacrifice a little sharpness with the reflex, but it still makes great images. Well worth the money for a telephoto lens.
